  2. Cyclonic rotation - Wikipedia

    en.wikipedia.org/wiki/Cyclonic_rotation

    Cyclonic rotation or cyclonic circulation is the atmospheric motion in the same direction as a planet's rotation, as opposed to anticyclonic rotation.In the case of Earth's rotation, the Coriolis effect causes cyclonic rotation to be in a counterclockwise direction in the Northern Hemisphere and clockwise in the Southern Hemisphere. [1]

  3. Anticyclonic tornado - Wikipedia

    en.wikipedia.org/wiki/Anticyclonic_tornado

    An anticyclonic tornado is a tornado which rotates in a clockwise direction in the Northern Hemisphere and a counterclockwise direction in the Southern Hemisphere. [1] The term is a naming convention denoting the anomaly from normal rotation which is cyclonic in upwards of 98 percent of tornadoes.

  4. Eddy pumping - Wikipedia

    en.wikipedia.org/wiki/Eddy_pumping

    Cyclonic eddies rotate anticlockwise (clockwise) in the Northern (Southern) hemisphere and have a cold core. Anticyclonic eddies rotate clockwise (anticlockwise) in the Northern (Southern) hemisphere and have a warm core. The temperature and salinity difference between the eddy core and the surrounding waters is the key element driving vertical ...

  5. Cyclone - Wikipedia

    en.wikipedia.org/wiki/Cyclone

    A polar cyclone is a low-pressure weather system, usually spanning 1,000 kilometres (620 mi) to 2,000 kilometres (1,200 mi), [54] in which the air circulates in a counterclockwise direction in the northern hemisphere, and a clockwise direction in the southern hemisphere. The Coriolis acceleration acting on the air masses moving poleward at high ...

  6. Anticyclone - Wikipedia

    en.wikipedia.org/wiki/Anticyclone

    An anticyclone is a weather phenomenon defined as a large-scale circulation of winds around a central region of high atmospheric pressure, clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere as viewed from above (opposite to a cyclone). [1]

  7. Mesocyclone - Wikipedia

    en.wikipedia.org/wiki/Mesocyclone

    A mesocyclone is a meso-gamma mesoscale (or storm scale) region of rotation , typically around 2 to 6 mi (3.2 to 9.7 km) in diameter, most often noticed on radar within thunderstorms. In the northern hemisphere it is usually located in the right rear flank (back edge with respect to direction of movement) of a supercell , or often on the ...

    Contrast cyclone. anticyclonic rotation anticyclonic storm Any storm system involving an anticyclone, in which winds circulate around a region of high pressure in the direction opposite to that expected around a region of low pressure. Anticyclonic storms rotate clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere.

    2. A "Hurricane" is also a tropical cyclone located at the North Atlantic Ocean or North-east Pacific Ocean which have an average storm activity and storms typically form between May 15 and November 30. 3. A "Cyclone" is a tropical cyclone that occurs in the South Pacific and Indian Oceans.
